Price increases on DIP parts?

[rockets4kids 204]

I was checking prices last night and noticed that the G2553 in PDIP has DOUBLED in price over the past four months.  This past spring it was pretty easy to find them for $1.25 @ qty. 25 and now everyone seems to be selling them for about $2.80.  SMD parts have not seen any change.

 

Does anyone know anything about this?  Is this temporary or permanent?

 

Avnet is running a special at the moment where you can pick up any qty @ $1.50 ea.  Consider this a heads up to anyone who likes the small DIP parts, or to anyone who might want to make a profit reselling them.

 

Sadly, if this is permanent, this is the final nail in the coffin for the MSP430 as far as I am concerned.  Please, TI, say it ain't so...

What dark alleys have you been buying parts from?

 

Prices always change. But from checking today.

Mouser has them for $3.04 @ qty 10. I would consider this a typical price. Funnily enough they're TSSOP is more expensive at $3.14.

 

I haven't seen anywhere that sell the PDIP for double the code of the TSSOP. I'd imagine your supplier may have bought a lot at an introductory reduced price and has only just exhausted stock.

The price history on octopart jives with my personal purchasing experiences:

From spring 2012 - Spring 2014 I had no troubles picking them up for $1.50/ea in relatively small quantities.

 

Octopart only seems to have data up to July 7, but you can clearly see the spike starting in late June.

 

For comparison, here is the price graph for the 20 pin TSSOP part:

I am finding several vendors selling the 20 and 28 pin TSSOP parts arround $1.50 @ qty 25, and none of them are listed as specials (the $1.50 price for qty. 1 PDIP at Avnet is listed as a "special deal")

 

If you've been paying $3 ea for these parts over the past two years you've been paying *way* too much.

Yeah I've been paying $2.50ish from mouser all these years. Oh well. Haven't bought all that many anyhow.

I'm not sure about DIP price increase, but LQFP pricing for the 550x series has definitely gone up for 25 quantity in the past year.

Nice find on the price history, that's a neat feature.

..and stock at the distributors get worryingly low, at least for the F5508 that I like to use.

Rochester stocks them for $3.00 a piece at qty of 1-24. Seems like a pretty good deal for you with about $10 shipping in the US. I have never bought anything from them before and probably never will since they charge $92 to ship to Australia.

Should I be worried that they call themselves "the world's most comprehensive solution for mature and end-of-life semiconductors"?

I've recently bought a hot air soldering "iron" as there are lots of ICs I want to play with but they only come in SMD packaging. I think DIP is really only released for hobbiests and old gear now as it is increasing rare to see PDIP offered. PDIP also uses more gold, the wires that go from die to pins is very thin gold, so the longer the distance the more gold. I know it's a very small amount but when you multiply it across 100,000 ICs it adds up.

[rockets4kids 204]

You don't need hot air to solder SMD, an iron will do just fine.  What you do need, though, is a professionally made board.  Although you can do 0.65mm pitch parts with homebrew PCBs it is still a bit tricky, at least for me, anyways.   The 2553 is my go-to part when I want to whip up a quick and simple one-off project on protoboard or a homebrew PCB.  If I'm going to spend $3, I'll be spending it on a much more powerful ARM part and a commercially-made break-out board.

I've had no problem with 0.65mm pitch TSSOP on home etched PCBs. 0.5mm LQFP to follow soon. I did use hot air to solder though.

 

Go SMD. You won't want to go back.

[PaulTech 2]

It's ok to use a soldering iron with 0805 or lager but once you start dealing with 0302 it all starts getting very tricky, they just seem to stick to the soldering iron. Yes , you can push them down but it can quickly becomes a 3 handed operation. And BGA? not talking about 200 pin BGA as do come as low as 4 pins(balls)

Is anyone interested in MSP430G2553IN20 (DIP20) @ $1.55 + $2.75 shipping (US only?)

[rockets4kids 204]

Do you think you'll be able to maintain that price?  If so, you'll definitely be getting my business when I need more!
